Work starts on Rampion Offshore Wind Farm


Work has begun at the Rampion Offshore Wind Farm, in readiness for the first foundation installation in January. This will include clearing boulders on the seabed along the cable route and around each of the 116 foundation positions to allow safe and effective installation.

Chris Tomlinson, E.ON Development Manager for the Rampion Offshore Wind Farm, said: “After five years in development, following successful consultation, consent and contracting, we’re delighted to be able to confirm that work will commence this week to prepare the seabed for turbine installation.

“Assessment of the number of boulders is still underway but is likely to be in the thousands and up to six vessels will be on site to undertake the work over the next many months. Great efforts will be made to replicate the seabed as it is now and all boulders moved will be weighed and the new position recorded. Details of the new positions of the boulders will be made freely available to sea users. We will continue to issue Notices to Mariners to keep sea users informed of these works.”

This coincides with work commencing onshore, with the first of 12 stages of the onshore project which started in early September to the south of the Upper Brighton Road, Worthing. Access points will be constructed first to allow construction of a haul road along the cable route. This will be followed by trenching works to lay the ducting for the cables, and finally, the reinstatement of the ground. Work will start on building the onshore substation in Twineham towards the end of September. “Throughout the Rampion project’s progress we’ve worked hard to keep the local community informed of our activities and over the last three months community events have been held at locations along the cable route in Lancing, Steyning, Henfield and Twineham, where we were pleased to be able to update over 500 local people of our construction plans” added Chris.

When the turbines are fully complete in early 2018 the electricity cables will come ashore at the Brooklands Pleasure Park in Worthing and will transport power along 27km of underground onshore cable to the new substation at Twineham where it will be connected to the grid.

During the planned 3 year offshore construction period it is estimated that around 250 to 300 jobs will be created. A workforce of up to 100 will be employed for the onshore cable route and around a further 40 to 60 people at the onshore substation during construction.  Once the wind farm is commissioned and fully operational, it is envisaged that up to 65 full time permanent jobs will be created at the operations and maintenance base which will be advertised locally and will include two apprenticeship roles per year for at least three years.

Approval has also been received from Lewes District Council Planning Committee for the wind farms operations and maintenance base at Newhaven Port. The design is expected to be finalised over the winter period with construction planned to commence later next year.

The 400MW 116 turbine project being built by E.ON and the UK Green Investment Bank plc (1) 13km off the Sussex coast will, when complete, provide enough electricity to supply the equivalent of around 300,000 homes (2) and reduce C02 emissions of up to 600,000 tonnes (3) a year.

The Rampion project remains set to become the first offshore wind farm off the south coast of England and is believed to be the first UK Round 3 project to enter construction. Anyone wishing to get in touch can contact us on 0800 280 0886, or email or visit
